Final answer:
The trigger mechanism of a powder-actuated tool resembles a hammer, with pulling the trigger initiating tool discharge through mechanical force.
Explanation:
Striking a hammer against a hard surface is an example of a mechanical force that can discharge a powder-actuated tool.
The trigger in a powder-actuated tool functions similarly to a hammer striking a surface; pulling the trigger releases a spring-loaded firing pin, resulting in the discharge of the tool.
Another example of mechanical force is pushing down on the pedal of a bicycle, which creates motion through force application.
